移动荷载作用下四种车桥耦合模型研究

Four kinds of loads moving vehicle-bridge coupled model

通过有限元软件ANSYS建立桥梁有限元模型,通过分析桥梁在移动荷载模型、移动质量模型、移动车轮加簧上质量模型以及四分之一车模型下挠度变化曲线,指出自重、惯性力、弹簧在桥梁挠度变形中起到的重要作用,比较四种方法的可靠性及其适用条件。

Through finite element analysis software ANSYS to build bridges finite element model, through the analysis of bridge load model in the mobile, mobile mass model, moving the wheel increases the quality and spring on the fourth vehicle model of the deflection curves, point- ing out that self-respect, inertia force, the spring in the bridge deflection deformation played an important role, comparing all four conditions of reliability of the method and its suitable condition.
